Personally, I use an extension that translates the game in real-time (English to Spanish), though I believe it only works for Unity games—whether Mono or IL2CPP (https://github.com/bbepis/XUnity.AutoTranslator/releases). You can use it if you like; feel free to look up a tutorial on YouTube or use AI to optimize it automatically.
P.S. I think it supports other languages too, but I recommend it for games that are originally in English or Japanese, as the translation quality tends to be better.
